Embodiment
[0046] Implementation of the present invention requires the AVI ultrasonic image video file collected by the ultrasonic equipment, use a computer cluster based on MPI as a parallel computing platform to carry out wide-view imaging, use a flat-panel display to display the user graphical interface, and can adopt C and C++ language to compile various types of The processing program can better implement the present invention.
[0047] Such as figure 1 (a), (b) and figure 2 As shown, in addition to the main thread, two other threads are created in the Master process: data reading thread and image stitching thread. When collecting in real time, the data reading thread builds a work pool according to user parameters, reads image data from the image acquisition card, divides the image data into small tasks and puts them into the task pool; when the imaging is image acquisition is completed, the data reading The thread builds a work pool according to user parameters, and divides the...

The invention discloses a parallel real-time medical ultrasonic wide-scene imaging method, which comprises the following steps of: dividing image registration and image splicing in a wide-scene imaging process into two processes capable of being executed in parallel by adopting a function division method; dividing an image registration task of an acquired ultrasonic image sequence into a plurality of subtasks by adopting a domain division method, and distributing the subtasks to different processors, wherein the processors cooperate with one another and execute the subtasks in parallel; and at the same time of image sequence registration and once the overall registration parameters of the images of the front part are acquired, splicing the images of the part, so that the image splicing process and the image registration process are superposed to shorten the imaging time and meet the requirement of real-time application. By the method, the parallel calculation technology is applied in the field of ultrasonic wide-scene imaging, so that the problem of long waiting time in wide-scene imaging is solved. According to the method, the parallel calculation environment is constructed by using a cheap calculation mechanism, so that the calculation resource can be fully utilized; and the method is simple and low in cost.
Description
technical field [0001] The invention relates to medical ultrasonic imaging technology, in particular to a parallel real-time medical ultrasonic wide-view imaging method. Background technique [0002] Ultrasound imaging has been widely used in clinical practice due to its advantages of convenience, no trauma, no pain, no ionizing radiation and low cost. Due to the limited divergence angle of the ultrasonic sound beam emitted by the traditional ultrasonic probe, and limited by the hardware conditions of the probe size, it can only generate an ultrasonic image with a narrow field of view and cannot reflect the overall image of the observed tissue, which affects the doctor's ability to diagnose accuracy. In response to this problem, in 1996, Weng et al. proposed ultrasonic wide-field imaging technology (Weng L, TriumalaiA P, Method and apparatus for generating large compound ultrasonic image. U.S. patent 5,575,286, November 19, 1996), which uses image registration technology T...
